I have successfully migrated from ISC DHCPv6 to Kea DHCPv6, now I would like to now migrate to Kea DHCPv4.
My first test is, enabling Kea DHCPv4 for a single "test" interface and check it works as expected. But currently it's failing.
The same interface works without issue with ISC DHCPv4. I am simply disabling ISC v4 for this interface, then enabling it for Kea. Same Interface IP, same DHPC IP pool.
But DHCP stops working then, DHCP requests are simply not answered (I launched wireshark on the computer to check this).
The laptop is directly wired to the igb3 interface on the DEC695. Is it not supported to have Kea DHCPv4 on one interface but ISC DHCPv4 on another?
If anyone has a pointer on what I should be checking, I would be grateful.
Have you checked with "sockstat -l" to see if the DHCP ports 67/68 are bound to KEA when you tried that?
Hello,
I think the below means it's not possible to run Kea DHCPv4 on some interfaces and ISC DHCPv4 on others:
root@opn:~ # sockstat -4 | grep :67
dhcpd dhcpd 96041 11 udp4 *:67 *:*
ISC seems to be binding against all interfaces by default, no matter which interface I have enabled it on.
Or am I reading this incorrectly?
No you are reading this correct so you have to disable all isc ranges before enabling KEA.
